- /* orinoco_cs.c 0.09b - (formerly known as dldwd_cs.c)
- *
- * A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
- * as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
- * EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and others).
- * It should also be usable on various Prism II based cards such as the
- * Linksys, D-Link and Farallon Skyline. It should also work on Symbol
- * cards such as the 3Com AirConnect and Ericsson WLAN.
